I don't know if you can find it in the UK. I looked at www.rileyblakedesigns.com, at their international distributors list here:

and it seems that the closest distributor is in Denmark. Do UK quilt shops get fabric shipped in from Denmark? Or Germany, or elsewhere in Europe? (That's something that I wouldn't know...)
